It’s the sort of gamesmanship that keeps readers turning the pages in a spy novel. The FBI says that Anonymous, the loose-knit collective of global hackers, intercepted a highly sensitive call between American cybercrime experts and their counterparts at Scotland Yard discussing, what else, Anonymous.

“The FBI might be curious how we’re able to continuously read their internal comms for some time now,” Anonymous teased in a Twitter message.

The 15 minute recording was released on Pastebin and then posted to Youtube. “I’m not sure if we’re the only two on here right now,” says an American agent named Bruce.

“Don’t say anything too bad, I’m on here with Matt,” replied his counterpart from Scotland yard. The group has a chuckle, unaware of the irony.

Anonymous also released an email with the time and password for the conference call, so they may have simply dialed in, rather than using more sophisticated techniques to intercept the conversation.

During the call the investigators discuss how they might proceed against Ryan Cleary and Jake Davis, two British suspects who are set to appear in court as suspected members of Anonymous. Highly sensitive tactics are discussed for when Scotland Yard might move to make further arrests and the evidence they are planning to bring to the trial.
